中文摘要
本研究的目的是利用奈米尺度的金属团簇所组成的金属岛薄膜,发展出具有高反射率及大光变的光碟记忆体。适用于光盘的金属是银和铜。我们选择了银岛膜并研究了它的记录特性。由于岛的热变形,银岛膜的光学性质可以通过加热在800 nm的波长处大大改变。我们已经通过实验证实了它使用原子力显微镜(AFM)的第一次。我们还看到了以大约1 μ s的记录速度的激光写入。此外,埋在含氟橡胶中的银岛膜被证实是非常稳定的。因此,我们认为银岛薄膜是一种非常有用的光盘存储介质。
英文摘要
The purpose of this study is to develop the optical disk memories with a high reflectance and great optical change by using metal island films composed of nanometer-size metal clusters. The suitable metals for optical disks are silver and copper. We have selected the silver island films and have investigated its recording characteristics. The optical properties of the silver island film can be greatly changed at the wavelength of 800 nm by heating due to the thermal deformation of islands. We have experimentally confirmed it by using an atomic force microscopy (AFM) for the first time. We have also seen the laser writing at the recording speed of about 1 mus. In addition, the silver island films buried in fluorine-contained rubber is confirmed to be very stable. Therefore we conclude that the silver island films are very useful media for optical disk memories.
